In this project we are going to discuss how to use Ultrasonic sensor (Distance /Range Finder) with arduino micro-controller .We will be getting the object distance or range of an object on the Serial ...

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

How to connect the HC-SR04 Ultrasonic Sensor to Raspberry PI & Arduino This repository is companion to the video below: ...

This Arduino Controlled Door alarm can be installed near the door to detect the presence of anybody at the door. Whenever somebody comes in the range of Ultrasonic sensor, buzzer starts beeping. You ...

The complete Arduino Levitation circuit is shown below and the working principle of the circuit is very simple. The main component of this project is an Arduino, L239D motor driving IC, and ultrasonic ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
